CLEANER FOR SPADING-HARROWS.

To ftl whom, it may concer/t:

Be it known that I, ANTON ANDERSON, a citizen of theUnited States,residing at Menomonie, in the county of Dunn and State of Visconsin,have invented a new and useful Improvement in Cleaners forSpading-Harrows, of which the following is a specification.

IIarrows of this character are to a large extent employed in preparingcorn-stubble ground for the sowing of a spring crop, as oats or thelike. To accomplish this result, the spades of the harrow are Ysoconstructed as to catch the corn-stubble and cut it between the spadesof the harrow and a shearing-blade or cleaner attached to the frame ofthe harrow for this purpose. Great trouble and inconvenience haveresulted in the use of these machines from this blade or cleanerbecoming displaced, bent, and failing to perform its functions properly.This objection I have obviated by the mechanism illustrated in theaccompanying drawings, in which- Figure 1 is a View of one of thespadingdisks with its head and cleaner from the lefthand side of themachine. Fig. 2 is a front view of the cleaner with a section of two ofthe spading-disks. Fig. 3 is a section of the lower end of the cleanermade at the line m x, showing one form of construction employed by me.Fig. 4 is similar to Fig. 3, but employs the construction of the lug 8,shown in Fig. 5. Fig. 5 shows a modification of the lug 8, designed tobe attached to the cleanerblade in any suitable manner.

1 is a portion of the frame of the harrow, to which is attached by thebolts 2 the cleaner 3, which cleaner or cutter approximates in shape atits outer edges to the shape of the spading-blades 4--that is, one sideof the blade or cleaner curves to correspond with and lie in closeproximity to the concave surface of one rotary spade or digger and theother side of the cleaner approximates the form and lies in closeproximity to the convex side of the next adjacent rotary spader ordigger.

The cleaner 3 consists of two side bars 13 and 14, these bars beingconnected by the cross-bar 15 and by the curved extension 16. The barsare preferably stiffened or strengthened by ribs 17 on the faces of suchbars opposite to the side against which the rotary diggers or spadesoperate to carry stalks and trash, as has been indicated.

The rotary spaders or diggers are of a form well known in this art, anexample of such being shown in the patent of Maul,No. 529,457, ofNovember 20, 1304. The spading-blades 4 4 are held between collars 5,mounted on axle A, the collars 5 being held apart by spacing-spools 6,mounted on said axle.

The blades 4 serve to stir or spade up the ground as the spading-harrowadvances. The

curved form of these spaders causes them to lift cornstalks and suchtrash and carry them up against the fiat faces of bars 13 14, and thesebars and the rotating spades act to shear or cut O such stalks and trashinto pieces of about the length of the distance between the rotatingspaders. The lower end of the cleaner 3 is curved forward and providedwith an integral tongue or extension 32, which tongue rests against thespool 6. As shown in Figs. 4 and 5, a tongue 8 may be made on a separatepiece and riveted to the curved bar 16 of the cleaner instead of beingmade integral. In either case this extension 8 or 32, bearing againstthe spool 6 on the axle A, serves to brace and support the lower end ofthe cleaner or cutter 3, the upper end of said cleaner or cutter beingsupported by the frame-bar 1 and the side bars 13 14 being braced bybars 15 and 16.

It is desirable that the cut trash may readily fall from the machine,and this is permitted by forming the cleaners 3 of solid side bars withopenings between, said bars being braced and supported, as described.

Spading-harrows having cutters or cleaners, as hereinbefore described,have proved very efficient and satisfactory in the field, where machinesof slightly-different construction have failed. I therefore contend thatthe device as a whole is a marked improvement. No such machine, so faras I am aware, can perform such Work as has been successfullyaccomplished by this machine.

1. The combination with a spading-harrow having rotating spadersconsisting of curved blades, of a cleaner attachment consisting of sidebars in proximity to Said rotating spaders and conforming to the outlineof the two adjacent diggers, said side bars having a crossbraee and anend piece supported against the spacing-piece on the di ggershaft, allsubstantially as described.

2. In a spading-harrow, the combination of the frame, the shaft havingrotating spadediggers, and the cleaner connected to the frame andbearing against a part on the shaft 1 on which the said diggers aremounted, said cleaner having integral side bars and a crossbraoestrengthened by a rib on the face opposite the cutting-face, the sidebars of such cleaner formed to lie in close proximity to the path ofmovementof the rotating diggers, al1 substantially as described.

ANTON ANDERSON. Vituesses:
